RTV Sealant

Room Temperature Vulcanizing (RTV) sealants are used in various applications on the 1.9L engine. Several factors need to be considered when servicing this material:
- Shelf Life-The useful shelf life of almost all RTV product is one year. Products used beyond this period will not perform as designed in some area of performance.
- RTV Instead of Gasket - RTV has certain limitations as far its performance under specific operating conditions. For this reason using RTV in an application where a gasket was originally used should not be attempted as the gasket has been specially designed for those applications.
- Color-RTV can normally be any color. High temperature resistance compounds are most likely red due to the addition of iron oxide. Other colors (black, white, blue or translucent) do not indicate any brand or physical characteristics.
- Several different RTV compounds are available which differ slightly in performance characteristics. Saturn P/N 21006236 (silver color) is specifically recommended for the engine and will attain excellent adhesive balance with good serviceability. Equivalent products may be used if Saturn material is not available, but they may not seal.
